主营：鞍钢镀锌卷 上海做鞍钢镀锌卷的公司

表面结构有普通钝化镀锌卷和环保钝化镀锌卷，产品主要用途为结构制管，欢迎新老客户前来选购。

我们在加工过程中，经常遇到各种各样的加工缺陷，比如折痕印，那么我们该怎么避免带钢产生折痕印，产生折痕印之后该怎么解决呢！

The surface structure has common passivation galvanized coil and environmental protection passivation galvanized coil. The main purpose of the product is structural pipe making. Welcome new and old customers to purchase.

In the process of processing, we often encounter a variety of processing defects, such as crease marks, so how can we avoid the strip to produce crease marks, and how to solve them after the crease marks are produced?

内圈折痕印的改善

折痕印的改善重点在于横切设备的选择和订货方式的变通。

1.钢带的厚度和强度是不能调整的，卷筒的涨紧力一般也没法选择，我们能做的就碰到厚度厚、材质软的钢卷时，尽量选择带橡胶衬筒的横切产线。

2.折痕印是卷状态下***的一种内圈形貌，可以通过横切线的精校设备改善。对于不希望有折痕印的用户，尽量选择那些拥有17辊、19辊或21辊精矫机并可分区调整压下量的横切产线。

Improvement of inner ring crease marks

The improvement of crease marks focuses on the selection of cross-cutting equipment and the flexibility of ordering mode.

1. The thickness and strength of the steel strip can not be adjusted, and the tension of the drum can not be chosen generally. What we can do is to choose the cross-cutting production line with rubber lining when we encounter the steel coil with thick thickness and soft material.

2. The crease mark is a special inner ring shape in the roll state, which can be improved by the precision calibration equipment of the transverse tangent. For users who do not want to have crease marks, try to select the cross cutting line with 17, 19 or 21 rolls fine straightener and adjust the reduction in different zones.

3.除此之外，一些特殊规格或材质，在社会上找不到合适的加工厂，那可以考虑加价定宝钢的出厂平板。一般来说钢厂的横切设备有更规范的作业和检修制度，设备配置也较好，同时对于内圈严重的折痕印会做分选处理。对于钢厂来说生产这种出厂平板，本身成本就比较高，所以相对来说加价也是合理的，不能用普通社会加工厂的价格进行对比。

钢厂在生产镀锌卷或冷轧卷的时候，会生产出个别降级产品，会标准各类缺陷名称，如：温度不符、速度不符等。

3. In addition, some special specifications or materials, in society can not find a suitable processing plant, that can be considered to increase the price of Baosteel&＃39;s factory plate. Generally speaking, the cross-cutting equipment in steel mills has more standardized operation and maintenance system, and the equipment configuration is better. Meanwhile, the serious crease marks in inner rings will be sorted. For steel mills, the cost of producing this kind of plate is relatively high, so the price increase is relatively reasonable, and can not be compared with the price of ordinary social processing plants.

In the production of galvanized or cold rolled coils, steel mills will produce individual degraded products, which will standardize the names of various defects, such as: temperature does not match, speed does not match, etc.

今天我们就来详细介绍一下这两个缺陷。

其实这两个缺陷都属于一种工艺缺陷：标准化产品的生产都需要符合标准化的工艺，超出了工艺控制要求的范围，就被称为工艺缺陷，这是一种钢厂内部控制的叫法。

温度不符和速度不符在冷轧产品和涂镀产品上常见的是和退火工艺相关的缺陷，通俗的说，连续退火工艺中，温度和速度就像烹饪时候的火候，工艺缺陷就是火候控制不佳。

举例说明：某个产品要求工艺段退火温度为750℃，允许偏差±20℃，如果实际退火温度高达800℃，这种产品就会被判定为温度不符。这就好比煮饭火大了，饭会焦。

某个产品使用连续退火工艺，退火速度要求300m/min，允许偏差±30m/min。实际生产时速度开到了350m/min，这种产品就会被判定为速度不符。

这就好比煮饭时间短了，饭会夹生。

那么，温度不符，速度不符对产品使用有什么危害呢？

这两种缺陷的危害，要看超出工艺标准多少。程度轻的可能只是力学性能超出标准几个Mpa，严重的话不但可能性能超出标准很多、或者整卷性能波动，甚至可能会附带有诸如氧化色、瓢曲等表面质量缺陷。
